I have an 3rd generation Apple TV which I use as a home hub. After remote access was disabled from Apple because of CVE-2017-13903 and turned on again with iOS 11.2.1 it stopped working remotely for shared users with the Apple TV.

I am a bit unhappy about this because I don't really use the Apple TV for watching, so it would be a bit overkill to buy a 4K one. What could I do?
